Dark Acrylic Front Panel: Show off your LED fans with the dark acrylic front panel with a mirror finish. The panel leaves a large gap for improved airflow.

Cooling Support: Supports up to 360mm radiator or 3x120mm fans at the front. 1x120mm fan or 120mm radiator at the rear, and 140mm fan at the top

Cooler Master MasterBox 5t Testing:

Testing involved recording temperatures in degrees Celsius for the CPU and GPU during idle and load phases. The load was simulated by running Prime95’s small FFTs and 3DMark Vantage for one hour. The maximum temperatures were recorded using HW Monitor 1.21.0. Please note that each case is tested from its factory setup, including location of fans, unless otherwise noted.

The case performance was about where I expected it to be and was right there with the other cases tested by OCC. When I examined the case with the FLIR camera, the heat was concentrated at the rear of the case, where the rear 120mm case exhaust fan and graphics card exhaust outlet are located. The rest of the case was cool and quiet. The way the front of the case is open with no obstructive optical drive bays and the option of using three 120mm or two 140mm fans, plus the ability to mount a 120mm or 140mm top exhaust fan, there are no concerns with air flow through the case. I did notice some air from the Noctua D14 cooler exiting through the vented top of the case, so I would expect even better cooling efficiency with the addition of a top mounted fan.

In the picture to the left is when the system is at idle. The color across the case is fairly consistent, showing an even temperature distribution. Not much heat is being generated at idle. But in the picture to the right, well, that is a different story. The CPU is being stressed with a mild overclock, which results in excess heat being pushed out by the rear exhaust fan. The D14 cooler directs the heat to the rear 120mm exhaust fan and out of the case. And as I mentioned above, I could feel some air exiting from the top vent, too, which is a good thing. Fresh air was drawn in from the front of the case by the front 120mm fan. Even with the fans at full speed, the case was quiet. The fan from the reference-style GTX Titan GPU (which is typically loud when running at full speed) was noticable, but that is pretty much the same with most cases I review. And being a reference-style, the temps of the GPU mirrored those from other cases since it pulls fresh air from inside the case and pushes it out the rear of the GPU. So unless something really obstructs the GPU air intake, the results won't really vary.
